How does donating blood plasma affect training?

If an athlete were to “donate” blood plasma for extra cash, how would this affect training?

Should they do it after training if possible?

Early in the morning so they have some hours before their training session?

And please, let’s not get into a discussion about the ethics of the matter.

What’s the sport and what’s the sex, height, and weight of the athlete?
